Application filed March 7, 1927. Serial No. 173,267.

My invention aims to rovide an improved flexible or arch-supporting shoe and insole therefor.

In the drawings, illustrating by way of eX- ample one embodiment of my invention Fig. 1 is a longitudinal, vertical section through the sole and heel portions of a shoe in` accordance with one form -of my invention, the shoe upper being indicated, in part, in dotted lines;

Fig. 2 is a bottom plan view of a. portion of the insole of Fig. 1

Fig. 3 is a view similar to Fig. 2 of another portion of said insole; and

Fig. 4 is a longitudinal, vertical section through the assembled insole and illustrating the same in a position assumed when the shoe is worn, for example during walking.

While my present invention is applicable to shoes of any type, I havey illustrated it in cluding (see Fig. 1) a usual or desired upper 1, an outsole 2 stitched to the welt 3, and a heel 4.

Referring more particularly to Figs. 2, 3 and 4, the insole comprises a. main or inner section, element, or member 5, seen in Fig. 2,-

and a supplemental and complementary outer section or element 6, which ma in some inv stances be formed integrally with said'main section-but is herein illustrated as a separate piece; seev Fig. 3. Said main or inner section is preferably of the usual full length and is provided on its lower face around the fore part with a suitable, marginal stitch-receivlng formation shown as comprising the par-` allel ribs or flaps 7, 7 turned up in the known manner from the adjacent face of the insole. Said rib formation, however, instead of continuing rearwardly alon the insole` in the usual manner to a point a jacent the heel, terminates at approximately mid-length of the main section 5, desirably just forward of the shank ortion and along a line 8 which is substantia ly the rear line oftheball of the sole.

The portion of said main or inner section of the insole to the rear of said line 8 may conveniently be referred to as the shank or rear part 9 of said section, including the shank proper and heel portions. Said shankpart 9 is preferably thinned or scarfed at its forwardend 10, Fig. 2 .a1ong aline substantially parallel or coincident with the line 8 above mentioned. Said inner insole section'is thus afordeda marked vflexibility in'the region of the-ball of the foot and particularly in the 'vicinit ofthe weakened area 10, at the juncture o the shank with the forepart ofthe insole. e

The supplemental or outer insole element 6, Fig. 3, is shaped and proportioned, desirably substantially as illustrated, to conform vto the rear part 9 of the main section.- As invided With a stitch-receiving formation similar to that on the main insole section and herein comprising the fia-ps or ribs 13, 13 which, when the inner and outer sections are assmbled, form a continuation of the flaps or ribs 7, 7 upon the inner section, and extend 75 rearwardly substantially to the heel. connection with a shoe of the welt type, in-

In assembling the insole the outer element 6 is placed fiatwise against the under face of the rear part 9 ofthe innerelem'ent 5 and, if

desired, cemented. or otherwise attached 8 thereto over` a limited `area of the'contacting faces at the forward end of the outer element.

Preferably, a cork or other filler 14 is inserted between the inner and outer sections of the insole at the shank. 'A fabric, preferably 85 innerstitch-receiving flap or rib and coextensive in length therewith. The complete in. sole thus assembled Vmay then be handled in the usual manner, the shoe upper and lining, together with the weltbeing secured by a usual inseam to the rib formation of the-insole, and the outsole in turn stitched to the Welt; A filling 16, Fig, 1, of any suitable maf terial may be provided intermediate the outsole and insole within the ribs 7, 7 and 13, 13.

From the foregloing description taken in ma connection with t e drawings, it willbe ap parent that in the finished shoe the upper and weltare directly secured only to the fore art of the inner insole section 5 from the toe ack to the break on the sole, herein at the line 8,

While rearwardly thereof the attachment of upper and welt is only to the outer or supplemental section 6 of the insole. At its rear in the vicinity of the heel seat, the supplemental insole sectlon is united tothe outsole 6 and to no l the heel in the usual manner, by nails, as indicated in Fig. 1. At least a major portion of the shank of the inner insole section, however, is left free to yield and move rela'- tively to theunderlying lower insole section, being separable from the latter.

The resulting action is substantially vas illustrated in Fig. 4. lThe inner insole sec tion, while free 4from the outer section, as

stated, is confined' at the heel by the surrounding counter or heel portion of the upper and, vif desired, it may be further secured by adhesive or other attachment tothe underlying section 6. When the heel is raised, as in walking, the inner section. 5 of the insole, flexing on the shorter radius and being confined only at its ends or end portions, is therefore caused to arch upwardly in the region of the shank, below the instep, substantially in the manner shown in said Fig. 4, and thus affords a flexible and conforming but upwardly pressing arch support of conscious and appreciable degree which makes for comfort and endurance both in standing or in walking.

My invention is not limited to the particular embodiment thereof shown and described,

its scope being pointed out in the following claims.

I claim:

1 An insole comprising a main element having a fore part adapted for attachment to the shoe upper and welt, and a rearpart including shank and heel ortions, a second element fitting flatwise agalnst said rear part 4provide ly on one and partly on the other thereof,

of the -mainelement and terminating at its forward end substantially in the rear line of the ball of the foot, said main element being scarfed'on its lower face to provide a shoulder against which the front-edge of said seclond element abuts, and a fabric reinforce on `the lower face ofthe fore part of said main element and overlapping onto the lower' face of said fecond element, said elements being with a marginalrib formation partwhereby the lshoe upper and welt may be attached to said secon element and to the fore part only of said main element, leaving the rear part ofthe latter free to flex relatively to the second element.

2.' An insole comprising an. element includl ling heel, shank, ball-and toe portions and having a' margmal, stitch-receiving forma` -t1on on nthe lower face of said ball and toe portions only,` and asecond element including only a heel and shank portion, mating with. said main element, the latter being recessed on its under face, the forward wall of sai'd recess ceive any end t rust 'of said second element and prevent relative forward movement thereof, and having only its forward portion attached thereto, said second element having on the under face of its shank portion a stitchreceiving formation providing a continuation of that on the rst element.

3. In an insole, a main section substantially the length ofthe shoe upper to which it providing a shoulder to reis to be attached, having a stitching rib around `v with a stitching rib inl continuation of that on said main section.

4. An'insole comprising an-innerportion 5,.

a shorter outer-portion 6 having its rear edge substantially coinciding with that of said inner portion,'said inner portion having a marginal, stitchreceiving formation 7,' 7I along that part of its'lower facewhich liesforwardly of said outer portion, andthe latter 'havinga similar-formation 13, 13-from its -forward extremity substantially to the heel,

and a layer of fabric v15 overlapping the exv'posed lower faces of said portions, a shoulder being formed on-l the lower face of said inner port-ion 5 along the ball line 8 constitut ingan abut-ment for the forward edge of said outer portion 6.

In testimony whereof, I have signed my -nameto this specification.

JOHN TMCISAAC.
